WATER-GATE.

SYECIFICATION forming part Of Letters Patent No. 581,538, dated April27, 1897.

Application filed May 25, 1896. Serial No. 592,928. (No model.)

To all whom it may concern.-

Be it known that I, JESSE T. DEAN, a citizen of the United States,residing at Clintonville, in the county of Coffee and State of Alabama,have invented certain new and useful Improvements in Water-Gates; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to water-gates.

The object of the invention is to provide a gate so constructed thatwater may automatically be maintained at a predetermined height in aflume or basin, which gate shall be simple and cheap in construction,not liable to get out of order, and which shall be reliable inoperation.

With this object in view the invention consists of a gate pivotallymounted in suitable uprights, a lever mounted adjacent to the gate andhaving one end adapted to bear against the gate to retain the same in aclosed position, a receptacle adapted to receive water and mounted onthe opposite end of the lever, and a trough having its receiving endcommunicating with 'a flume or basin and having its discharge end overthe receptacle on the lever.

Further, the invention consists of various novel detailsof constructionand combination of parts whereby the object of the invention isaccomplished and the effectiveness of the device is insured.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a side elevation of a gate constructed in accordance with myinvention, one side of the frame of the gate being broken away, theparts being shown by full lines in the position assumed when the gate isclosed and indotted lines in the position assumed when the gate is open;and Fig. 2 is a plan view of the gate.

In the drawings, A represents the gate, which is pivotally mounted on arod 0;, having bearings in the frame B, in which the gate is placed. Thepoint at which the gate is pivoted is preferably a distance from thebottom a bevel a at the top where the end of the lever 0 bears againstit, and the end of the lever is correspondingly beveled at the end 0Placed upon the lever 0 adjacent to the beveled end 0 is a weight 0which is somewhat greater than the normal weight of that part of thelever on the opposite side of the pivot to that on which the weight isplaced. The end of the lever opposite to that which bears against thegate is provided with a receptacle 0 having in the bottom thereof anopening 0 the receptacle being of such capacity that when filled withwater the end of the lever carrying the receptacle will be heavier thanthat of the end which bears against the gate.

Adjacent to the gate and placed at a height at which it is desired tomaintain the water in the flume or basin is a trough D. One end d ofthis trough communicates with the basin or flume and the other end d isarranged immediately above the receptacle 0 In the use of the gate theparts are normally set in the position shown by full lines in Fig. 1,and this position will by the described construction and arrangement ofthe parts be maintained until the water'in the fiume or basin rises to apointjto flow through the troughD. When this takes place, the waterflowing through the trough is discharged into the receptacle 0, and assoon as sufficient weight is imposed upon the end of the lever O,carrying the receptacle, to overbalance the weight 0 the beveled end ofthe lever is removed from the gate. The gate being mounted, asdescribed, will be opened by the pressure of water and will remain openuntil the level of the water is but a short distance above the point 'atwhich the gate is pivoted. At this point theipressureion the lowerportion of the gatejwill close it. When the water ceases flowing intothe receptacle 0 the latter, being buoyant, Will discharge its loadthrough the opening in its bottom, and when the receptacle is empty theWeight will return the lever to its initial position.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

1. A Water-gate pivotally mounted in suitable uprights, a lever mountedadjacent to the gate and having one end adapted to bear against the gateto retain the same in a closed position, a receptacle adapted to receiveWater and mounted on the opposite end of the lever, and a troughcommunicating with a flume or basin and having its discharge endarranged above the receptacle, substantially as described.

2. A gate pivotally mounted in suitable uprights, a lever mountedadjacent to the gate disconnected therefrom and adapted to bear againstthe gate to retain the same in a closed position, the lever beingprovided adjacent to its end adapted to bear against the gate, with aWeight, and the other end with a receptacle, and a trough having one endcommunicating with a basin or flume and having its other end arrangedover the receptacle on the lever, substantially as described.

3. A gate pi votally mounted in suitable uprights and provided with abevel at its upper end, a disconnected lever mounted adjacent to thegate and having one of its ends beveled and arranged adjacent to thebevel on the gate, a Weight arranged on the lever adjacent to the endbearing against the'gate, a receptacle arranged at the opposite end ofthe lever, the receptacle being buoyant and being provided in its bottomWith an opening, and a trough communicating at one end with a basin orflume and having its other end arranged above the receptacle,substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
